CLAIM OF PRIORITY TO PRIOR APPLICATION

This patent application claims priority to U.S. provisional patentapplication No. 60/799,201, filed May 9, 2006, the disclosure of whichis incorporated herein in its entirety by reference.

FIELD OF THE INVENTION

A surface treatment apparatus for accessing and treating surfacesincludes a lockable universal positioning joint to permit the apparatusto be articulated and configured in an ergonomically safe andcomfortable user form factor.

BACKGROUND

Accessing and contacting surfaces that are typically difficult orimpossible to reach with a human arm, or with the assistance of tools orimplements that help to extend the length of a user's arm, often requirethe user to be located in an uncomfortable and unsafe position. Priorart tools and implements exist that help to extend the length of a humanarm for purposes of accessing and contacting a surface, such as, forcleaning, treating, sealing, polishing, painting, texturizing, sanding,and otherwise affecting the surface. Such tools and implements howeveroften position an end user in an uncomfortable position such that theuser experiences body and arm strain in an effort to appropriately use atool. In addition, a user's efforts to employ a particular tool orimplement may place the user in an unsafe or dangerous position.Further, a tool or implement may not be appropriately and effectivelyemployed, and therefore does not achieve its full potential, because ofa user's inability to safely and comfortably use the tool or implement.In the context of window cleaning, this is apparent whereby prior arttools or implements often require a user to be in an uncomfortableand/or unsafe position when attempting to access and contact difficultto reach areas of window surfaces, such as, for example, exterior windowsurfaces and window surfaces of relatively tall and wide windows.

For purposes of disclosure, and not to limit the invention, theinvention is described below in the context of window cleaning and theapparatus includes a window cleaning apparatus and the application headincludes a cleaning head constructed and arranged to contact and cleaninterior and exterior window surfaces. Those of ordinary skill in theart will appreciate other embodiments of the surface treatment apparatusaccording to the invention are possible that incorporate one or moreapplication heads and implements, each constructed and arranged toperform one or more functions in a variety of surface treatmentapplications including, but not limited to, treating, sealing,polishing, painting, texturizing, sanding and otherwise affecting asurface. Other embodiments are within the scope of the invention.

Referring to FIG. 1, in an aspect, the invention provides a windowcleaning apparatus 10 including a cleaning head 12, a lockable swivelarm 14, a lockable universal positioning joint 16, an extendible wand18, and a handle 20. The lockable universal positioning joint 16 and thelockable swivel arm 14 are constructed and arranged to adjustablyarticulate the apparatus 10 such that the cleaning head 12 is disposedat an optimal angle or orientation relative to the extendible wand 18and a user's hand and arm to enable the user to safely and comfortablycontact the window surface with the cleaning head 12 and to move thecleaning head 12 along the window surface in an effective andcomfortable motion or stroke. The extendible wand 18 adjustablyconfigures the apparatus 10 with sufficient length to permit a user toaccess all portions of window surface, such as difficult to reachexterior surfaces.

Referring to FIGS. 2-3, and with further reference to FIG. 1, the swivelarm 14 and/or the universal joint 16 adjust the apparatus 10 and, inparticular, adjust the geometry of the cleaning head 12 and theextendible wand 18 relative to one another and to a user's hand and arm,while the extendible wand 18 adjusts the length L₁ of the apparatus 10,to help to configure the apparatus 10 for use in cleaning differenttypes and sizes of windows. As shown in FIGS. 2 and 3, a user appliesthe apparatus 10 to clean an exterior window surface of a casementwindow whereby the extendible wand 18 provides sufficient length L₁ topermit the user to reach all areas of the window surface, includingdifficult to reach areas, with the cleaning head 12 without the userextending their arm far outside the window and without the userexperiencing body strain and discomfort. The length L₁ of the extendiblewand 18 is slidably adjustable, as shown by arrow 300 in FIG. 1. Theswivel arm 14 and/or the universal positioning joint 16 position thecleaning head 12 at an optimal geometry for a particular cleaningapplication. As described below, the swivel arm 14 and/or the extendiblewand 18 pivot about the universal position joint 16, as shown by arrow200 in FIG. 1 to adjust the geometry of the cleaning head 12 and theextendible wand 18 and a user's hand and arm. As shown in FIGS. 2 and 3,the cleaning head 12 is positioned in a substantially perpendicularorientation relative to the extendible wand 18 and above a user's handand arm to enable access to exterior surfaces of a window, while theuser remains in a safe and comfortable position inside the windowcasement. In addition, the geometry of the cleaning head 12 relative tothe extendible wand 18 and a user's hand and arm helps to permit theuser to safely and comfortably move the cleaning head 12 along theexterior window surface. As shown in FIGS. 2 and 3, a user performs avertical cleaning motion or stroke from inside the window casement.

As described below, the swivel arm 14 further disposes the cleaning head12 by pivoting, as shown by arrow 100 in FIG. 1, to position or anglethe cleaning head 12 toward a window surface to help to facilitateeffective contact of the cleaning head 12 with the window surface.

In addition, as shown in FIG. 3 and as will be described below, theapparatus 10 defines a low or narrow profile to permit the apparatus 10to extend between two panes of, for instance, a double hung window toenable window surface cleaning. As described above, the geometry of thecleaning head 12 relative to the extendible wand 18 and a user's arm andhand help to facilitate access to difficult to reach window surfaces,such as those shown, and to enable the user to safely and comfortablyclean such surfaces.

Referring to FIGS. 4-5, and with further reference to FIG. 1, the swivelarm 14 and/or the universal joint 12 also position the cleaning head 12in a substantially horizontal orientation relative to the extendiblewand 18 and a user's hand whereby the cleaning head 12 is horizontallyparallel to the wand 18 and a user's hand. In addition, the cleaninghead 12 may be further aligned with the wand 18 and a user's hand todispose the head 12 at approximately the same height as the wand 18 andthe user's hand. This configuration of the apparatus 10 is useful forcleaning exterior surfaces of windows that are relatively wide and wouldtypically require a user to reach far outside a window casement, withdifficulty, danger and discomfort to the user, to enable the user toreach all areas of an exterior window surface. As mentioned, the lengthL₁ of the extendible wand 18 configures the apparatus 10 with sufficientlength to enable a user to reach all areas of an exterior surface of awide window with the cleaning head 12 without the user dangerouslyextending their arm or body far outside the window and experiencing bodyand arm strain. The swivel arm 14 and/or the universal joint 16 disposethe cleaning head 12 at an optimal geometry relative to the wand 18 anda user's hand to help to achieve effective contact of the cleaning head12 with a window surface and to enable the user to safely andcomfortably move the cleaning head 12 along the window surface in anupward/downward vertical motion or stroke.

In addition, configuration or orientation of the apparatus 10, as shownin FIGS. 2-5, may be adjusted, e.g., turned about 45 degrees, such thata user can employ the apparatus 10 to accomplish a safe and comfortableback and forth horizontal motion or stroke across a window surface.Further, the cleaning head 12 and the extendible wand 18 may define anyother geometry than those shown in FIGS. 2-5 to position or orient thecleaning head 12 relative to a user's hand and/or arm and to optimize aform factor the apparatus 10 defines relative to a particular type andsize of window.

Referring to FIG. 6, and with further reference to FIG. 1, the cleaninghead 12 is a low profile member including at least one cleaningimplement, such as, for instance, a wiper blade 12A, as shown in FIGS. 1and 6. Preferably, the cleaning head 12 is an elongated member and theat least one cleaning implement covers at least a portion of the lengthof the member to provide the apparatus 10 with sufficient and effectivesurface cleaning area. The length of the cleaning head 12 and thecleaning implement may be any of a range of lengths, depending upon thewindow cleaning application.

The cleaning head 12 may be one-sided, wherein the cleaning head 12includes a single implement, such as the wiper blade 10A, disposed alonga first side of the cleaning head 12. Optionally, the cleaning head 12may be two-sided, wherein a second implement, such as, for instance, ascrubber rail or sponge 12B, may be disposed along a second side of thecleaning head 12, e.g., opposite to the first side, as shown in FIGS. 1and 6, to incorporate the cleaning head 12 with multiple functions. Inaddition, the implement and, in particular, the wiper blade 10A and thescrubber rail or sponge 12B may be removably secured to the cleaninghead 12 such that the wiper blade 10A and the rail or sponge 10B can beremoved for cleaning, storage, or repair or for replacement with othercleaning implements. The invention is not limited to the type ofimplement disposed along the cleaning head 12 and envisions the cleaninghead 12 is configured to accept any of variety of other implementsincluding, but not limited to, a scraper, a brush, a roller, a drier, anapplicator, and any other implement configured to clean, treat and/orotherwise contact a window surface for a particular application.

The wiper 12A and the scrubber rail or sponge 12B are disposed andangled along at least a portion of the length of the cleaning head 12and are configured to contact a surface, e.g., substantially the entirelength of the wiper 12A or the scrubber rail or sponge 12B contacts asurface, to be cleaned.

The interior of the cleaning head 12 defines an internal fluid channel12C configured to receive fluid from a fluid channel the interior of theswivel arm 14 defines, as described below. The internal fluid channel12C extends along at least a portion of the interior of the cleaninghead 12 to distribute fluid through the member. The cleaning head 12further includes one or more spray jets or nozzles 12D disposed alongthe cleaning head 12 and configured in fluid communication with theinternal fluid channel 12C. Each spray jet or nozzle 12D includes anoutlet 12E configured in fluid communication with the internal fluidchannel 12C to receive fluid from the channel 12C to enable the jet ornozzle 12D to express fluid from the cleaning head 12. The jets ornozzles 12D may be positioned substantially equidistant from one anotheralong the cleaning head 12. Optionally, one or more of the jets ornozzles 12D are adjustable such that the positions of the outlets 12Eare altered to change the direction in which the jets or nozzles 12Dexpress fluid.

As shown in FIGS. 1 and 6, the jets or nozzles 12D are disposed alongthe second side of the cleaning head 12 preferably above the scrubberrail or sponge 12B, or other implement(s), to express fluid from thecleaning head 12 above the rail or sponge 12B to a surface to becleaned. For instance, when the rail or sponge 12B contacts a surface tobe cleaned, one or more jets or nozzles 12D express fluid above the railor sponge 12B to help to prevent running or streaking of fluid along thesurface below the rail or sponge 12B to thereby facilitate efficientapplication of fluid and surface cleaning. Alternatively, oradditionally, the jets or nozzles 12D may be disposed along the firstside of the cleaning head 12 above the wiper blade 12A, or otherimplement(s).

FIG. 6 illustrates a cross-sectional view of the low profile of thecleaning head 12 that results from the compact dimensions of thecleaning head 12 and the low profile of the wiper blade 12A, thescrubber rail or sponge 12B, and/or the plurality of jets or nozzles12D. As shown, the cleaning head 12 may define a width W₁ that isrelatively narrow, e.g., approximately one inch or two inches. Inaddition, the width W₁ of the cleaning head 12 may be related to theapplication, e.g., the type of windows or other surfaces, in which theapparatus 10 is being used. As an example, FIG. 6 shows the cleaninghead 12 positioned between the separate panes 60A and 60B of a doublehung window, illustrating the low profile of the cleaning head 12 thatpermits the apparatus 10 and, in particular, the cleaning head 12 toaccess the interior surfaces of the panes 60A and 60B for cleaning.

With further reference to FIG. 1, the lockable swivel arm 14 isconnected to a terminal end 12F of the cleaning head 12 and isconfigured to swivel or pivot, as shown by arrow 100 in FIG. 1, about alockable swivel joint 14A to permit adjustment of a position or an angleof the cleaning head 12. The swivel arm 14 includes a first portion 14Bconnected to the cleaning head terminal end 12F and slidably received bya second portion 14C that is connected to the lockable universalpositioning joint 16. The swivel joint 14A is defined at about the pointat which the first and the second portions 14B and 14C interface and isconstructed and arranged to releasably lock the first and the secondportions 14B and 14C and to permit the portions 14B and 14C to pivotabout one another, as shown by arrow 100 in FIG. 1, when disposed in anunlocked position. The swivel joint 14A may include any of a variety oflocking mechanisms constructed and arranged to releasably lock the firstand second portions 14B and 14C in place to securely position the swivelarm 14 and the cleaning head 12 at a desired or required position orangle. Suitable locking mechanisms enable the swivel joint 14A to beconfigured as a fluid tight joint and may include, but are not limitedto, screw clamps, cam locks, collet locks, ratchet locks, frictionclamps, tooth locking mechanisms, cammed magnetic locks, magnetic cablelocks and similar configurations.

When unlocked, the swivel joint 14A helps to facilitate positionadjustment and angling of the cleaning head 12 relative to a surface tobe cleaned such that the cleaning head 12 effectively contacts thesurface for cleaning. In addition, the swivel arm 14 helps to furtherfacilitate adjustment of a position and/or an angle of the cleaning head12 to help configure an optimal geometry of the cleaning head 12relative to the extendible wand 18 such that a user of the apparatus 10achieves, as described above, an ergonomically comfortable and effectiveextension of the apparatus 10 and a cleaning motion or stroke of thecleaning head 12. Further, the swivel arm 14 helps to angle or positionthe cleaning head 12 to enable a user to manipulate the apparatus 10and/or the cleaning head 12 to move around obstacles in the path of thecleaning head 12. The cleaning head 12 permits a user to move around ornext to, for instance, window frames, panes, and other obstacles with acomfortable and effective cleaning motion or stroke.

As shown in FIGS. 1-5, the first portion 14B of the swivel arm 14defines a right angle to dispose the cleaning head 12 at a distance fromthe extendible wand 18 sufficient to permit pivoting movement andangling adjustment of the cleaning head 12 toward a window surface tofacilitate effective contact of the cleaning head 12 with the windowsurface. The angle of the swivel arm 14 also helps to dispose theuniversal locking joint 16 at a position opposite to the cleaning head12 that is in alignment with approximately the center of the elongatedcleaning head 12, as shown in FIG. 1. In this configuration, theapparatus 10 conveys pressure or force that a user applies to theapparatus 10 to the cleaning head 12, such that, the pressure or forcethe cleaning head 12 applies to a surface is substantially consistentalong at least a portion of the length of the cleaning head 12 incontact with the surface. The contact the cleaning head 12A makes with asurface and the pressure or force the cleaning head 12 applies to thesurface, e.g., during movement of the cleaning head 12 along thesurface, is substantially consistent along at least a portion of thelength of the cleaning head 12 in contact with the surface. For example,when a user applies pressure or force to the apparatus 10 configured asshown in FIG. 1, the wiper blade 12A contacts and applies pressure orforce to a surface substantially consistently along at least a portionof its length in contact with a surface. As a result, the motion orstroke of the wiper blade 12A along a surface is more consistent andeffective.

The angle of the swivel arm 14 further helps a user of the apparatus 10to manipulate or work the cleaning head 12, and, more particularly, anycleaning implement attached to the cleaning head 12, into comers andnarrow openings, around or adjacent obstacles in the cleaning head path,such as window panes and frames, and other difficult to access or cleanareas of window surfaces.

Still referring to FIG. 1, and with further reference to FIGS. 2-5, theapparatus 10 includes the lockable universal positioning joint 16constructed and arranged to articulate the apparatus 10 whereby aposition or an angle of the cleaning head 12 relative to the swivel arm14, the extendible wand 18 and/or the handle 20 is achieved toadjustably position or orient the cleaning head 12 and/or the extendiblewand 18 at an appropriate and optimal geometry. As mentioned, theuniversal joint 16 configures the apparatus 10 in an ergonomically safe,comfortable and effective user form factor. Such form factor enables auser to access difficult to reach areas of window surfaces with theapparatus 10 and to produce an effective and comfortable cleaning motionor stroke along window surfaces with the cleaning head 12 while the userremains in a safe and comfortable position inside window casements. Theform factor also helps to eliminate the need for a user to extend theirarm and/or body dangerously and/or uncomfortably outside a windowcasement.

As shown in FIGS. 2-5, the joint 16 permits the swivel arm 14 and/or theextendible wand 18 to pivot, in a direction shown by arrow 200 in FIG.1, about the joint 16 to position or orient the cleaning head 12 in avariety of positions relative to the swivel arm 14, the extendible wand18, and/or the handle 20, as may be required or desired for a particularapplication. The geometry of the cleaning head 12 relative to theextendible wand 18, the swivel arm 14 and/or the handle 20 may permit auser's hand and arm to be disposed approximately below the cleaning head12 during use of the apparatus 10, or to be disposed parallel to and,optionally, inline with the cleaning head 12 to configure the apparatus10 in the required or desired form factor.

The universal positioning joint 16 includes a locking mechanismconstructed and arranged to releasably and securely lock the swivel arm14 and the extendible wand 18 in a given position and is configured as afluid tight joint. Suitable locking mechanisms include, but are notlimited to, screw clamps, cam locks, collet locks, ratchet locks,friction claims and any locking configurations or combinations.

With further reference to FIG. 1, an interior of the swivel arm 14defines an internal fluid supply channel (not shown) that is disposed influid communication with an internal fluid supply channel (not shown)that an interior of the positioning joint 16 defines.
